The index of refraction is calculated from the observed refraction angle using Snell's law. For mixtures, the index of refraction then allows to determine the concentration using mixing rules such as the Gladstone–Dale relation and ...

This difference helps drive the refractive power of the crystalline lens. If the refractive index of the lens increases, light undergoes more refraction; thus, a myopic shift will occur.
